IMPROVEMENT IN RAILWAY-CAR JOURNAL-BOXES.

Specification forming part of Letters Patent No. 140,568, dated July 8, 1873; application filed May 28,1873.

To all whom it may concern:

Be it known that I, RICHARD N. ALLEN, of Pittsford, in the county of Rutland and State of Vermont, have invented a certain new and Improved Railway-Car Journal-Box; and I do hereby declare that the following is a full, clear, and complete description thereof, reference being had to the accompanying drawings making part of the same.

Figure l is an inside view of a section of an axle-box. Fig. 2 is a vertical longitudinal seetion. Fig. 3 is an end View. Fig. 4 is a transverse vertical section. Fig. 5 is an end view having the lining detached. Fig. 6 is a-side view. Figs. 7 and 8 are detached sections. Fig. 9is a detached section of a journal.

Like letters of reference refer to like -parts in the several views.

The rst part of this invention relates to the construction of a j ournal-box for railway cars; and secondly to :the lining of said box, which consists of alternate layers of lead and paper 3 and the object thereof is to provide the journal with a seat that shall be slow to excite frictional heat, and at the sanne time offer a firm, solid, and lasting bearing-surface for the journal.

The following is a more full description of the above-specified invention.

The part A in the drawings represents a car axle-box cap, which is or may be of the usual shape. The inside of each upper edge of the cap is rabbeted out, forming a shoulder, B, Fig. 5, in which is fitted a cleat or fillet, C, Fig. 3, a detached view of one of which is shown in Fig. 8. Said fillets are retained in place by pins a, or by other suitable means.

The inside of the fillets is concave, thereby forming a continuation of the curve of the axle-box or cap thereof, as shown in Fig. 3.

The middle part of each of the shoulders B is removed, forming a recess indicated by the dotted lines b, Fig. 5, a transverse section of which is shown in Fig. 4, the purpose of which will presently be shown. The axle-box or cap referred to is lined partially with alternating sheets of lead and sheets of thick paper or paper board. A detached view of such lining is shown in Fig. 7, in which c and d are sheets of lead, and fand g layers or sheets of paper board. It will be observed that a sheet of lead is the surface of the lining, whereas the lowest sheet or layer is paper, and that the paper sheets are much thicker than the lead sheets. One purpose of the thick sheets of paper is to give strength and solidity to the sheets of lead.

The above-described lining is secured in the box or cap from working therefrom endwse by having each edge of the lining project outward, forming a sort of flange or wing of the inside section of each edge, as shown at b', Fig. 4, and which is of the exact size to fit in the recesses of the shoulders above referred to. Said projections are represented as being fitted therein in the transverse section,

Fig. 4.

The lining is prevented from working out transversely, or in the direction of the curve of the box by the fillets O, which t down upon the lining, thereby holding it securely in place.

D represents a section of a journal, in the seat of which, Fig. 9, is a detached section.

The advantage of a journal-box made as above described is, that when the lining is Worn out it can be easily replaced by another by simply removing the fillets. The lining, being ofno considerable thickness, nor of hard material, can be readily fitted in the place of the old one, and at Inueh vless expense than the ordinary homogeneous metalseats in cornmon use. n

In allowing thel journal to run upon a lead surface, friction thereby is much reduced; hence the journal is less liable to heat, and will wear longer.

The sheets of lead being laid upon alternate layers of paper or paper board gives to the lining a substantial and iirm character, so that it will successfully bear the weight ofthe journal and imposed load thereon, and the paper being a poor conductor of heat the tendency thereof will be to keep the journal cool.
